March 6: IRSST Releases Pamphlet on Hypothenar Hammer Syndrome

Hypothenar Hammer Syndrome (HHS) is an insidious disease that can be easily confused with other disorders, such as hand-arm vibration syndrome or Raynaud’s disease. The disease develops in workers who use vibrating tools or who repeatedly use the palms of their hands to strike, flatten, press or twist objects. To educate employers and workers on HHS, the IRRST published an information pamphlet entitled Recognizing Hypothenar Hammer Syndrome.
